Worldwide Patents? No! I guess it would depend on what you meant by "Worldwide".
From the companies website:
The Company has been recently awarded patents for its sulfide process in the United States of America. The issue of patents by the US Government is a strong endorsement of the originality of the Nichromet process both from a chemistry standpoint as well as an economic standpoint: the process can recover precious metals in a three-hour cycle as opposed to a 40-hour cycle for cyanide Patents for its sulfide process have been also issued in Cuba, Guatemala, and Peru.
Patents are pending in Chile, Mexico, Canada, Indonesia, Philippines, and Dominican Republic.
Nichromet Extraction Inc has obtained patents for the extraction of nickel and magnesium from laterites in Canada, Guatemala, Cuba and Panama. Patents are pending in Brazil, Colombia, Dominican Republic, Venezuela and Australia.s
But this is good news to those individuals who hold an interest in this private company I suspect.
